About these units
Road speeds are given in kilometers per hour in most countries and in miles per hour in the US and the UK. 1 mph is exactly 1.609344 km/h, because a mile is 1,609.344 m. Science and engineering use meters per second (1 m/s = 3.6 km/h), and ships and aircraft use knots: one nautical mile (1,852 m) per hour, about 1.852 km/h or 1.151 mph.
FAQ
› How do I convert kn to km/h?
1 kn = 1.852 km/h. To convert, multiply the value by 1.852: 2 kn = 3.704 km/h.
› What is 1 km/h in kn?
1 km/h = 0.5399568035 kn. The reverse formula is kn = km/h ÷ 1.852.
› How do I convert km/h to m/s quickly?
Divide by 3.6. For example, 90 km/h is 25 m/s; to go back, multiply m/s by 3.6.
› Why do ships and planes use knots?
A nautical mile matches one minute of latitude, so speeds in knots fit naturally with navigation charts.
